AUTOMATIC DAM PER-REGULATO R.

SPECIFICATION forming part of Letters Patent No. 315,904, dated April 14, 1885.

Application filed December 529, 1634. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN BURGE, a citizen of the United States, residing at Vestfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Automatic Damper-Regulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to certain improvements in automatic damper-regulators which can be set to open or close a damper or other similar device at any desired time.

It consists of certain novel construction and arrangement of the various parts, all of which I will now proceed to point out and describe, reference being bad to the accompanying drawin gs, in which Figure 1 is aside elevation. tail view of some of the parts.

Referring to said drawings, A is a plate secured to a suitable vertical frame or wall. B is a lever pivoted at one end to the lower part of the plate A, and is connected by a chain, a, or othersuitable means, with the damper,which may be setto open or close by the falling of said lever B. b is a projection on the plate A, and has the incline surface b,on which the lever B rests. G is astop which limits the downward movement of the lever. D is a latch pivoted to the upper part of the plate A, and is provided on its lower end with the wedgeshaped point (I. Said point d coming between the lever B and plate A as the latch falls forces said le- Fig. 2 is a dever off the incline b and causes it to drop to the position shown in dotted lines. E is alever-arm pivoted at one end to the frame or wall at a point above the plate A, and having its free end 6 bent in toward the wall. 6 is a rod connecting the lever-arm with the latch E. F is a rotating disk having the notch f. On the periphery of the disk the end 6 of the lever-arm E rests. Said disk is so arranged that suitable device with adamper or valve which is set to open or close when the lever falls from the incline. The end 6 of the arm E rests upon the periphery of the disk F and holds the lever B on the incline surface I) by means of the connecting-rod e. The disk F is then set to rotate, so that the notch'f will come directly under the end 0 of the arm E at any desired time. When the notch f comes under the end of the arm, it drops into said notch, as shown in dotted lines, and causes the latch D to fall. The wedge-shaped point (2 coming between the lever B and plate A causes said lever B to drop to position shown in dotted lines, and thus operates the damper or valve.

Having thus fully described my invention, I claim as new and desire to secure by Letters Pat ent 1. The plate A, having the projection b,and lever B,pivoted to said plate A,in combination with the latch D, having the wedge shaped point d, substantially as shown and described.

2. The disk F, adapted to be rotated and having the notch f, the arm E, connecting-rod e, and latch D, having wedge-shaped point (i, in combination with leverB and projection b, all arranged and operating substantially as shown and described.

In testimony whereof Iafiix my signature in presence of two witnesses.

JOHN BURGE.
